MACHINE FOR PERFORATING PAPER FROM ROLLS.

Application filed September 24, 1925. Serial No. 58,463.

This invention relates to a novel and improved machine for marking paper, such as is used for example in wrapping various articles and more particularly to a lnachine for pelrforating paper as itis unwound from a r0 1.

One of the objects of my invention is to provide a machine of the above character which will perforate the paper in the manner desired and which shall do so without danger of tearing or mutilating the same. This object I achieve by employing a roll having means thereon to perforate the paper as it passes the same, but which is not positively rotated, the rotation being caused by the paper itself.

Another object of my invention is -to provide a machine for perforating paper which shall contain improved means for varying the characters formed by the perforations. This I achieve by providing the roll with a plurality of segments so constructed that they may be readily applied to and detached from the roll and each of which has a separate character formed by needles secured thereto.

Further objects of my invention reside in the novel arrangement of elements which provide means for removing and adjusting the roll which carries the perforating means and also the guide roll co-acting therewith; which provide means for keeping the two rolls in alignment; which provide means for readily attaching segments to and detaching them from a roll; and which provide improved means for securing the needles to each segment, these needles forming the character identifying that segment.

In the accompanying drawings I have shown a selected embodiment of my invention.

Fig. 1 is a perspective view of a piece of paper perforated by my invention.

Fig. 2 is a side elevation of the machine forming my invention.

Fig. 3 is a rear elevation of the structure shown in Fig. 2, this view being taken from the left of said Fig. 2.

Fig. 4 is an exploded view of the needle roll showing the manner of attaching a segment thereto.

Fig. 5 is a longitudinal sectional view through the two rolls at theirpoint of contact and showing the means for the needles to a segment.

Referring now to the drawings 1 designates fastening any suitable frame which may be employed to support thereon a roll of paper 2 from which the paper is unwound as it is perforated, the perforating taking place as the paper passes between the needle roll 3 and the guide roll 4 which rolls are also mounted in the frame.

' I prefer to mount the rolls so that they may e readily removed and adjusted. Various means may be devised for this purpose, but I have shown the needle roll 3 supported on a shaft 3 mountedin bearings 5, each bearing being inserted in place at the bottom of a slot 6 in a standard 7 forming part of the frame. The top of each slot is closed by a swinging block 8 pivoted at 9 on the top of standards, whereby the bearings are held in place in the slots in the standards. The upper roll may be removed from the frame by first loosenlng the tension devices 12 and swinging the blocks 8 to one side so that the bearings 5 may be moved upwardly and through the ends of the slots 6. The lower roll 4 may then be removed from the frame by moving the bearings 15 up into the openings 16 which are of sufiicient size to permit sidewise movement of the bearings 15 therethrough. Adjustment of the roll 4 is effected by adjusting screws 17 disposed in each of the standards 7 and contacting with bearings 15.

Referring now more particularly to Figs. 3 and 4, it will be seen that the needle roll 3 has a portion 18 which is continuous and that this portion terminates in a shoulder 19 in which are provided a plurality of apertures 20. Received on the reduced portion 21 of the roll 3 are a plurality of segments 22 each of which is provided at its end with a projection 23 adapted to be received within one of the apertures 20. The number of segments corresponds to the number of apertures whereby the roll will be completed and present a continuous surface.

obtain various combinations of characters.

Each segment has a certain character thereon formed by a plurality of needles. These needles may be secured to the segment in any desired manner, but I prefer to fasten them in position by means of a plate 24 secured to the body 25 of the segment as by screws 26. The plate is provided with apertures extending therethrough, these apertures being arranged in the form of the desired character and being countersunk at the inner surface of the plate in order to receive the heads of the needles 27. This construction is very fully illustrated in Fig. 5.

' In operation the segments are arranged upon the reduced portion 21 of the needle roll to. form the desired combination of characters. Each segment will have its projection 23 received within a corresponding aperture 20 and each segment will be held in correct position by this engagement and also by engagement of the end 28 of the segment with the shoulder 19. Preferably the surface of the roll is completed by addition of the requisite number of segments so as to leave no gap between segments. A sufiicient number of blank segments may be provided for this purpose. When the segments are in place they are secured by means of a spring clamp 29, which is adapted to be received within the grooves 30in the ends of the segments. These grooves will be in alignment to form one continuous groove, when the segments are all in place. The clamp is made in the form-of a wire ring terminating in handles 31 and 32 which, when pressed together will expand the ring sufficiently so that it may be removed. Endwise movement of the segments 7 is prevented by means of a peripheral shoulder 33 at the end of the reduced portion 21 which shoulder engages the outer ends of the segments.

The needle roll 3 is provided with a peripheral guide 34 engaging in a peripheral guide groove 35 upon the guide roll 4. By this means relative longitudinal movement between the two rolls is prevented. This is very important because such movement might cause displacement of the paper and might also cause damage to the needles 27. The result would be an inaccurate perforating of the paper. The guide roll 4 is further provided with a plurality of peripheral grooves 36 to receive the needles 27. It will be noted that the needles are all disposed upon certain circumferences of the roll 3. That is, a circumference drawn through any one needle will pass through one or more needles in every other character on the roll and all needles are disposed on these circumferences so that they will register with the grooves 36.

paper as shown in Fig. 1.

The machine which I have disclosed above is one which will avoid tearing of the paper '37 which is fed between the rolls. It will be noted that neither roll has any positive driving means, the rotation being caused entirely by the passageof paper therebetween. As shown in Fig. 2 the paper 37 is taken off the roll 2 and trained over the roll 4 and beneath the roll 3. Then as it is pulled off by suitable means (not shown) the two rolls will be rotated and the needles 27 will form the perforated characters 38 in the The segments may be readily removed and changed or replaced so as to provide different combinations of characters or so as to renew a damaged segment if necessary. The number of parts is small and they are of such character as not to be easily damaged. The accuracy of the work is insured by the guide means 34 and 35 and further by the fact that the peripheral speed of the needle roll is the same as the lineal speed of the paper. There is no chance of mutilation of the paper because of different rates of the speed of the paper and the perforating means.

I am aware that changes in the form, construction and arrangement of parts may be made without departing from the spirit and without sacrificing the advantages of the invention and I reserve the right .to make all such changes as fairly fall within the scope of the following claims.
